BBT1729K BigTop Multi-Flue Chimney Cover, Black Galvanized Steel, 8" H x 17" x 29" - with Minimum 20" x 32" Required Overall Chimney Dimension

This was a fairly easy job once I figured out what was needed to complete it.1) You will need a hammer drill. I got a hyper tough hammer drill from wal mart for about eighteen dollars.2) You need a caulking gun3) You need a 1/4 ratchet and an 8mm socket to torque down the masonry screws into the holes you drilled (learned this the hard way, don't use a flathead screwdriver)4) You need a marker to mark the outline of the cap to caulk inside that lineThere may be more you need, but that's all I can think of. I did use duck bill pliers to bend the tabs that join the cage part of the cap. You obviously want to assemble the cap first, before taking it up to the roof. Place it how you want it on the chimney, use a sharpie to draw the outline of its current placement and to mark the holes you will drill. Remove the cap. Drill your holes with a 3/16 masonry drill bit. Put a bead of caulk inside the sharpie line (don't cover up your drill holes, I left 2 inches on either side). Next place your cap back on the caulk and line up the drill holes. When putting in the masonry screws that come with the cap, start them with a #2 screwdriver, and then switch over to a 1/4 ratchet with an 8mm socket to screw them down tight. I really bloodied up my hands trying to use a screwdriver to tighten as they kept scraping the cage. That's it. Mine is the stainless model so I cleaned it up with some glass cleaner and all done.I really like the cap. Seems well made and made here in the USA. Came with caulk (mine was punctured so I reinforced it with duct tape before using), screws, and nuts to fasten the top to the cage. Simple and straightforward once you have everything ready.

What can I say? This unit fit perfectly, and there are so many different sizes that you're bound to be able to find one that fits your chimney. It comes with everything you need, including the sealant. The flat pieces just hook together with tabs and then the top screws on to hold it rigid until installation. The only thing that puzzles me is why it costs so much more to get a slightly taller unit. (You can check this out and see what I mean.) The only thing required to make one of these 4" taller is to increase the side pieces 4" in one direction. (Obviously, the top part would be identical.) I figured I'd get a slightly taller one, but it cost so much more that I quickly dropped that idea. Anyway, nice-looking and does the trick!

Compared to any other options I could find for a chimney cap, this was, by far, the most economical, and I am very happy with the results. I didn't realize that it came with a tube of adhesive caulking, so I had already purchased some, however when the tube rolled out of the package I was pleasantly surprised. After I had carried it all up onto my roof, drilled the mounting holes, and began to try to squeeze out the adhesive, I wished I had carried the tubes that I had purchased separately up onto the roof. The Adhesive is incredibly stiff and hard to extrude; I was concerned that I was going to bend my caulking gun. Also, it wanted to stick to the tip of the tube more than the top of the chimney, so I was constantly twisting the caulking gun around and trying to smear the big blobs of adhesive onto where they needed to go.It was nearly impossible to create an even bead of adhesive around the perimeter. I doubt it really matters though, the cap is held on securely with screws and I'm not sure a complete seal around the perimeter is even a very good idea. The top of my chimney is almost perfectly flat so having a few spots where water that blows under the cap can drain away is probably sensible. It was a chilly day, (30 degrees F) when I installed it so maybe warming up the tube would have made the process easier, however I'm just guessing.

I got this for our farmhouse. It had BBQ grates over the openings to the double flukes. I ordered a 49 in by 17 by 8, but I received a 53 in by 17 by 14 in. For this reason, I knocking a star. It still fits on the chimney so I went ahead and installed it. The product is good, went together pretty easily, is sturdy enough to last a good while and do its job, Came with all the hardware needed to install, complete with 2 tubes of adhesive if needed. In my case, I felt like 10 tight screws into the mason would hold just fine. My only concern is with it being so high,wind driven rain will still make its way in to easily.

I bought this to place on the chimney of the wood-fired oven I built recently. I modified it in order to mount it in the cement rather than mount it with screws on the outside of the cement. In order to make it easier to do so, I spot welded the corners together so they would be rigid when I placed it in the cement (see photos of completed mounting). Otherwise, they will probably not center well on the cement. It is not made of heavy materials but is adequate for the job. But be careful when handling it because it can be dented fairly easily. It assembles easily and is attractive when placed.

I put this on a Patio fireplace . I was anxious because it is sandstone top of chimney and afraid the drilling may crack it.It arrived without the attaching bolts but a call to company support and the sent them right away. Could have got them at the hardware store as well but the company came through fine.Setting it on top of the chimney before bolting down it seems a bit flimsy. After install it is rock solid. I added a couple for extra bolts just because we have so much wind. The drilling was a breeze so I worried for nothing. Used the silicone provided and it looks great, you can remove the top four nuts to clean the chimney if you want as well. I recommend it.
